Like the other comment said, the barrel is not the firearm. If you have parts, tools, and things that could feasibly make a gun then they can charge you with possession of a gun. Firearm laws are complex and difficult. And honestly it would probably be easier and safer to try to use replica/prop parts just to avoid issues.
No. As they said, the receiver is the firearm, not the barrel. As long as the receiver is intact, you can replace the barrel and have a functional gun.
Couldn’t you just weld the barrel sealed like they do for prop guns?
